Abstract

PROCEDE ET DISPOSITIF POUR LA COUVERTURE DE LA CHARGE DE POINTE DU CYCLE PRINCIPAL D'UNE CENTRALE THERMIQUE. ON ASSOCIE UN CYCLE AUXILIAIRE AVEC UN ACCUMULATEUR D'EAU QUI PEUT ETRE CHARGE A PARTIR DU CYCLE PRINCIPAL. ON DETEND PAR LAMINAGE LE FLUIDE PORTEUR D'ENERGIE AINSI EMMAGASINE, LA PARTIE DEGAGEE SOUS FORME DE VAPEUR FOURNIT ALORS DU TRAVAIL DANS UNE TURBINE PRINCIPALE QUI A ETE DIMENSIONNEE POUR CELA, TANDIS QUE LA PARTIE NON VAPORISEE EST REINTRODUITE DANS LE CYCLE PRINCIPAL, DE TELLE SORTE QUE L'ON SUPPRIME LES PRELEVEMENTS PAR LES SOUTIRAGES A BASSE PRESSION ET QUE L'ON AUGMENTE LA PUISSANCE DE LA TURBINE PRINCIPALE. L'ALIMENTATION DE L'ACCUMULATEUR D'EAU PEUT SE FAIRE AVANTAGEUSEMENT AVEC L'EAU DE CONDENSATION DU RESURCHAUFFEUR. APPLICATIONS AUX CENTRALES NUCLEAIRES AVEC REACTEURS A EAU LEGERE.METHOD AND DEVICE FOR COVERING THE MAIN CYCLE POINT LOAD OF A THERMAL POWER PLANT. AN AUXILIARY CYCLE IS ASSOCIATED WITH A WATER ACCUMULATOR WHICH CAN BE CHARGED FROM THE MAIN CYCLE. BY ROLLING THE ENERGY CARRIER FLUID IS EXPANDED THUS STORED, THE PART DISCHARGED IN THE FORM OF VAPOR IS PROVIDED DURING THE WORK IN A MAIN TURBINE WHICH HAS BEEN DIMENSIONED FOR THIS, WHILE THE NON-VAPORIZED PART IS REINTRODUCED INTO THE CYCLE. SO THAT THE WITHDRAWALS ARE REMOVED BY THE LOW PRESSURE TAPPINGS AND THAT THE POWER OF THE MAIN TURBINE IS INCREASED. SUPPLYING THE WATER ACCUMULATOR CAN BE USED WITH CONDENSATION FROM THE RESURHEATER. APPLICATIONS TO NUCLEAR POWER PLANTS WITH LIGHT WATER REACTORS.
